A very similar query was posted on a forum recently:
<http://subversion.wandisco.com/forums/2-general-support-and-troubleshooting/178-repository-disk-space-analysis-tools.html>.
In that case, that user, Trent, had a similar situation and was
investigating quite deeply (One thing he said was, '[...] I do a "cat"
of the current and previous revisions and then run "xdelta" on those
files under the assumption that will approximate how much space that
revision occupies.' And, 'I picked a revision, and got the involved
files... they totaled 336k and the delta from the last version was about
90k. But the revision file in the repository was over 2 gigs!')
I suggested that he might like to contact the dev list to get further
help in debugging the problem, but he has not done so yet.
Kevin might find it useful to compare notes or talk to Trent.
